Static Ruby Monthly The only newsletter dedicated to static typing in Ruby Welcome to another issue of the Newsletter! September arrives with a subtle change in season and a clear shift in how typing tools fit into daily development. With RubyConf 2026 session recordings rolling out, discussions about language evolution and runtime capabilities are everywhere. On the Technology for Humans podcast, Charles Oliver Nutter explored the present and future of JRuby, highlighting how WebAssembly...
Static Ruby Monthly | Issue 19, August 2026
Static Ruby Monthly The only newsletter dedicated to static typing in Ruby Welcome to another issue of the Newsletter! August is here, bringing the peak of summer and another lively round of developer debates over whether dynamically typed languages are pretty much dead. But as the Ruby ecosystem continues to show, the real answer is not a forced choice between unconstrained dynamism and rigid ceremony. It is about gradual tools that meet developers where they work. In her Brighton Ruby talk,...

Static Ruby Monthly The only newsletter dedicated to static typing in Ruby Welcome to another issue of the Newsletter! July has arrived, actually it is almost over, bringing a fascinating wave of innovation to the static Ruby ecosystem. While summer often slows things down, this month is full of experiments that push static typing beyond traditional boundaries. From JVM integrations to AST-aware signature synthesis and new compiled language experiments, the community is finding novel ways to...
Static Ruby Monthly | Issue 17, June 2026
Static Ruby Monthly The only newsletter dedicated to static typing in Ruby Welcome to another issue of the Newsletter! Summer is finally here, and today I have the smallest newsletter so far for you. Either it is the summer sun keeping everyone busy and away from contributing to static typing gems, or maybe it is AI. Perhaps AI just needs guidance rather than tools, as it is already using types just fine with what it has. Either way, the static Ruby world continues to mature with a balance of...
Static Ruby Monthly | Issue 16, May 2026
Static Ruby Monthly The only newsletter dedicated to static typing in Ruby Welcome to another issue of the Newsletter! This month feels a bit slower than usual. It seems the debates around whether to use types in Ruby have settled. The sides have been chosen, and the community is now channeling its energy into building solid tools instead of arguing on social media. The focus has shifted from “why” to “how,” and the tooling ecosystem is maturing nicely. A standout release this month comes...
Static Ruby Monthly | Issue 15, April 2026
Static Ruby Monthly The only newsletter dedicated to static typing in Ruby Welcome to another issue of the Newsletter! April is already here, meaning we have passed the first third of the year. Time certainly flies. In my recent blog post I tried to reflect on where Ruby is heading. It looks like it is far from dead, and with the current AI era, it may gain even more traction, potentially reaching the fame it had fifteen years ago. While there are still debates on whether static typing is...
Ruby: Where are we going? 2026 Edition
Ruby: Where are we going? 2026 Edition This is more of a self-reflection rather than a proper blog post. I dedicated the last 6 years to working with static typing in Ruby. You can find my Udemy course about RBS and static typing in general, or sign-up for my upcoming book about the same topic. I never realised how static typing can be important until I started spending more time with staticly typed languages like Java or Kotlin. Every time I came back to Ruby, the lack of types drove me...
Static Ruby Monthly | Issue 14, March 2026
Static Ruby Monthly The only newsletter dedicated to static typing in Ruby Welcome to another issue of the Newsletter! Ruby’s relationship with static typing has always been complicated. Type systems used to feel optional. Something for the disciplined, or for teams at large companies. But in early 2026, something shifted. AI coding agents changed the equation entirely. Type systems went from nice-to-have to essential infrastructure. This month’s update captures that shift. It’s not about any...
T-Ruby: Adding Static Typing Without Runtime Overhead
T-Ruby: the TypeScript for Ruby Static typing is a formidable tool that brings immense value to codebases of all sizes. From tiny scripts to massive monoliths, the benefits are hard to ignore: you get live documentation that is always up to date, enhanced readability, and a reliable safety net that significantly boosts code reliability. Different dynamic languages have taken various paths to solve the typing puzzle. Python introduced native but optional type hints, while the JavaScript...
Static Ruby Monthly | Issue 13, February 2026
Static Ruby Monthly The only newsletter dedicated to static typing in Ruby Welcome to another issue of the Newsletter! Life moves fast, and the last year proved it. Andrej Karpathy named vibe coding just one year ago, and it already feels like a different era. Ruby static typing has the same energy, with steady progress mixed with fresh experiments and new workflows. Last year gave us new gems that feel like early signals of where we are going. low type and t-ruby hint at bold directions,...
